"So long as the engine is in good tune and overall good shape, and your oil & coolant levels are good, you can bounce off the Rev Limiter all day":
Well, not really. I can think of several negatives here:
1-Even if you engine doesn't blow at that time, you are shortening your overall engine life. Wasting tons of gas too!
2-Each trip to the rev limiter is recorded by the ECU. This is read when you get your car serviced at Porsche and if you are under warranty, can SOMETIMES be used to deny an engine warranty claim. The data becomes part of your PERMANENT RECORD!
3-If you are going this fast all the time, the Police and the local tire dealer will be your best friends!
Happy motoring!
